Inferring Parameters of a Relational System of Preferences from Assignment Examples using an Evolutionary Algorithm
(2019-05-07)Most evolutionary multi-objective algorithms perform poorly in many-objective problems. They normally do not make selective pressure towards the Region of Interest (RoI), the privileged zone in the Pareto frontier that ... -
Reconstruction of PET Images Using Cross-Entropy and Field of Experts
(2019-01-18)The reconstruction of positron emission tomography data is a difficult task, particularly at low count rates because Poisson noise has a significant influence on the statistical uncertainty of positron emission tomography ... -
Gene selection and disease prediction from gene expression data using a two-stage hetero-associative memory
(2019-04-01)In general, gene expression microarrays consist of a vast number of genes and very few samples, which represents a critical challenge for disease prediction and diagnosis. This paper develops a two-stage algorithm that ... -
A Distributed Localization Algorithm for Wireless Sensor Networks Based on Robust Statistic
(2018-12-16)This research presents a distributed and low-complexity algorithm for range-based localization in wireless sensor networks (WSNs). The proposed method uses robust functions suitable to avoid outliers derived from corrupted ... -
Compress sensing algorithm for estimation of signals in sensor networks
(2019-06-07)In this research, we present a data recovery scheme for wireless sensor networks. In some sensor networks, each node must be able to recover the complete information of the network, which leads to the problem of the high ... -
